Abstract

In the pursuit of enhancing and optimizing the efficiency of Proton Exchange Membrane Fuel Cell (PEMFC) systems, the utilization of linear controllers for DC/DC converters is a prevalent practice. However, the use of these classical controllers introduces the issue of slow response time, under/overshooting, and highly oscillatory dynamics during system responses. In light of these drawbacks, this paper presents the design and assessment of a non-linear approach based on a Sliding Mode Control with Exponential Reaching Law (SMC-ERL) as a viable solution. The stability of the closed-loop control is ensured through the Lyapunov approach. The efficacy of the proposed control methodology has been assessed via comparative analysis within the Matlab/Simulink environment, encompassing two distinct scenarios, response to dynamic variations in current references and load fluctuations. The obtained results prove that the designed SMC-ERL achieves the fastest convergence with a reduction of steady-state error compared to the PI controller allowing for robust and precise control.
